PREFACE

THE following account of the plants of the Oban District of
South Nigeria has been drawn up from the collections made by
Mr. and Mrs. P. Amaury Talbot in the years 1909 to 1912,
during Mr. Talbot/s period of Government service in the District,
„and presented by them to the Museum. Mrs. Talbot also made
a very large and beautiful series of drawings of the plants,
reproductions of which she proposes to publish in a separate book.

The plants have been determined and the novelties described
by members of the Department of Botany, with the assistance
of Mr. 8. Moore in various orders, Mr. H. N. Ridley who has
worked out the Zingiberacee and Marantacex, and Miss A.
Lorrain Smith who has determined the Lichens. For descrip-
tions of a few new species I am indebted to Mr. Sprague and
Mr. Hutchinson of the Herbarium of the Royal Gardens, Kew.
The authorship of each portion of the work is indicated exactly
in the text.

Mr. Talbot has supplied a short account of the district and of
the general character of its vegetation; and notes on many of
the plants by Mr. and Mrs. Talbot are incorporated with the
descriptive matter. :

INTRODUCTION

Tux following notes on the general character and vegetation of
the Oban district have been kindly supplied by Mr. Talbot.

The Oban district of South Nigeria * lies within the bend of
the Cross River at a distance of 40 to 100 miles from the Gulf
of Guinea. It is bounded on the East by the German Cameroons,
of which it is, botanically speaking, an offshoot, though apparently
exceeding its neighbour in the luxuriance of its vegetation.
Throughout the length and breadth of the land hardly a level
spot is to be found. The average height above the sea-line varies
from about 300 to 900 feet, with masses of hills rising towards
the centre into a clearly marked watershed, nearly 4000 feet
high. The greater number of these hills have been climbed by
us, but haighé seemed hardly to influence the luxuriance, or even
type, of vegetation.

The rocks of the district are very ancient and consist
mostly of gneiss or granite, pierced by veins of iron ore-
and other minerals. The weathering of these has produced a
soil very favourable to growth. This, mixed with the deep
accumulation of rich vegetable humus and mould in the dense
shade of these tropical forests, forms, in the warm damp climate,
a kind of vast natural forcing bed, from which spring an almost
inexhaustible variety of flowering plants and trees. These grow
up with such incredible rapidity that I have found it difficult to
recognise sites, which were under cultivation five years before.
The land is drained by a close network of rivers, which meander
through the deep green of the “bush,” like the veins of some
giant leaf, or leap down the hill-sides in a series of cancigies and
waterfalls.

The forests of Oban are usually described as within the ever-
green belt, but, though evergreens predominate, more careful
study discloses the presence of a very large proportion of
deciduous trees, many of which burst into leaf and flower twice

* A map of the district will be found with Mr. Talbot's communication
to the Geographical J enge en 637).

vili INTRODUCTION

every year. Several are even known to bloom four times in the -
year, while on the other hand some cauliflorous trees only blossom
every two or three years. Natives, whose information in other
cases proved trustworthy, declared that certain ones only flower
once in seven years.

The number of different species to be found in these forests is
immense and may be computed to average at least 400 to 500
distinet species to the square mile. Among these are to be found
a large number of valuable economie trees, such as cam-wood,
ebony, rubbers and mahoganies of enormous size, scented and
otherwise. The state of age gradation among all such trees is
more satisfactory too in this district than that in the greater
part of the Protectorate.

The annual rainfall, carefully kept during my tenure of office,
averages 175 inches, and the humidity may be a contributory
cause to the extraordinary large number of cauliflorous trees.
The unusual rainfall and the heavy dews, which last all through
the dry season, act too as protective agents in rendering impossible
destruction by forest fires.

A very considerable part of the district has at one time or
other been under cultivation. The system of farming consists in
roughly clearing the land in January and February, by cutting
and burning the smaller growth, while the great trees are left
standing. This has, however, affected the type of forest less
than would otherwise have been the case, owing partly to the
scanty population, about four to the square mile, and also to the
large number of trees, which, according to the superstition of
the people, must neither be destroyed nor planted, but left
untroubled by human interference. A considerable part of the
land may be regarded as virgin bush, and is perhaps the only:
important survival of that vast primeval belt, which once
extended over the greater part of South Nigeria.

In order to be convinced that the forests of Oban are to a
great extent true primary forest one has only to leave a native
path in the remote parts of the interior and cut one's way for a
short distance through the tangle of lianes, often of the girth of
our Northern tree-trunks, which hang between giant boles, 200 to
300 feet high, and, in the case of cotton trees, over 80 feet in cir-
cumference. Oncethe path has been lost sight of, one may wander
for days without coming across a trace of human habitation.

INTRODUCTION 1x

The collection includes 1,016 species and varieties, 195 of
which are new; there are nine new genera. The new genera
are Alphonseopsis and Dennettia in the order Anonacem, the
former allied to the Indian genus Alphonsea, the latter to
Melodorum ; Crateranthus, a genus of Myrtacesw intermediate in
structure between Napoleona and the tropical South American
Asteranthos ; Afrohamelia (Rubiaces) most nearly allied to the
tropieal American Hamelia, and, in the same order, Dorothea
and Diplosporopsis, new members of the tribe Gardenieæ, and
Globulostylis, the affinity of which is with Cuviera in the tribe
Vangueriex ; Scyphostrychnos (Loganiaces) closely allied to Strych-
nos; Talbotia,* a member of the tribe Justiciææ in the order
Acanthacex ; and Amauriella, a member of the subfamily Philo-
dendroide in Araces.

Of the new species seven belong to the order Anonaces,
three to Violaces, three to Guttifer®, one to Malvaces, six to
Sterculiacez, including four new Colas, two to Geraniaces, two
to Meliacex, two to Olacacex, one to Celastracee, three to
Sapindacem, three to Anacardiacew, five to Leguminos®, one to
Rosacew, eight to Myrtacee six of which belong to the genus
Napoleona, three to Melastomace:, thirty-four to Rubiaceæ, one
to Ebenace», one to Oleacee, twelve to Apocynacem, four to
Asclepiadacex, nine to Loganiacex, one to Convolvulacew, one
to Pedalinesm, twenty-one to Acanthacee, four to Verbenaces,
three to Aristolochiacex, three to Laurinew, two to Euphorbia-
cer, twenty to Orchidace:, two to Liliacez, and three to Aracem.

A few specimens have been included in the enumeration
which were collected on a journey through Nigeria and the North
Cameroons to the Bornu Country and Lake Chad ; the locality
of these is indicated in each case. A full list of the plants
collected on this journey forms an Appendix to Miss O. Macleod's
“ Chiefs and Cities of Central Africa."

Mr. Talbot refers to the extraordinary large number of cauli-
florous trees and special attention was paid to these when collect-
ing, and Mrs. Talbot has also made careful coloured drawings of
the flowers. Many of them are new. Such are several species _
of Cola, Napoleona and Drypetes, species of Tetrastemma,
Omphalocarpum, Diospyros and others.

* This is equivalent to Afrofittonia Lindau in Engl. Jahrb. xlix. 406,
published March 28, 1913, and thus too late for notice in this memoir.

X INTRODUCTION

A valuable discovery from an economic point of view is that
of Poga oleosa Pierre (Rhizophoracee), hitherto known only
from the Gaboon, the seeds of which are remarkably rich in oil.

As indicated in Mr. Talbot’s note the district adjoins the
Cameroons and is botanically an extension of the evergreen rain-
forest area of that district. The systematic list shews that the
flora is practically identical with that of the Cameroons; a pro-
portion approaching half the plants collected has hitherto been
known only from that area. Apart from this endemic or
Cameroons element there is a strong representation of what may
be called the Gulf of Guinea flora, that is of species more or less
widely distributed from Sierra Leone to the Gaboon. The more
Southern Congo-Angolan element is much less marked and the
collection contains comparatively few plants representing a
general tropical African distribution.

In the determination of the plants considerable help has been
obtained from the rich tropical African material in the Herbarium
of the Royal Gardens, Kew ; our thanks are due to the Director
for some determinations in the order Euphorbiacex, and also
to members of the Staff for advice kindly given in connection
with other orders. Specimens of a large proportion of Mr. and
Mrs. Talbot's plants have also been presented to Kew.—-[A. B. R.]

ANONACER.

THE collection contains a remarkable number of curious and
interesting ınembers of this family. There are two new genera,
Dennettia and Alphonseopsis. The former belongs to the tribe
Xylopiee and is allied to Melodorum, the latter is allied to the
Indian genus Alphonsea. Uvaria obanensis sp. nov. is a showy
plant with large flowers generally in fascicles of three ; and Uvaria
anonoides sp. nov. is closely allied to U. latifolia Scott Elliot.
There are good specimens of Pachypodanthium Staudtii Engler
& Diels, which has not been previously recorded for Nigeria.
Unona obanensis sp. nov. is closely allied to U. hirsuta Benth. ;
and U. Millenii Engler & Diels was previously known only from
Lagos. '

There ‚are four species of Monodora and two species of
Tetrastemma ; one of the latter is probably T. Solheidii De
Wild., previously known from the Congo, the other has much
larger flowers (4-5 cm. long), but we await better material.

The affinity of this genus is with Uvariastrum Engler, which has
flowers with three large sepals, outer petals much longer than the
inner, and bilobed, verrucose stigmas. Jt is also near the Indian
genus Alphonsea Hook. f. & Thoms., but its calyx and the con-
nection of its stamens are quite different. `

Oban; n. 1496. South Nigeria, Dennett, n. 44 (Herb. Kew.)

Leaves 9-14 cm. long, 4:5-6 cm. broad; lateral nerves not -
conspicuous, glabrous except the midrib; petioles 3-4 mm. long.
Peduncles short. Petals 8, uniseriately valvate, 10-11 mm. long.
Stamens about 1 mm. long.

A very curious and interesting tree, at once distinguished by the
2 rarely 3 sepals, the 3 rather thick, concave, valvate petals, the
numerous small stamens with the connective very slightly produced
and the 15-20 carpels with the ovules biseriately arranged.

Named in honour of Mr. R. E. Dennett, who first collected this
tree in Southern Nigeria and whose specimens are in the Kew
Herbarium.

The alliance of this genus is with Thonnera, but the flowers are
hermaphrodite and not on long peduncles, and the receptacle is a
different shape. Mr. H. N. Ridley, who kindly examined this plant,
considers that it should be placed in the Group Xylopieæ next to
Melodorum. It is also allied to certain rather abnormal species of
Anona of the Sect. Atte, especially A. echinata Dunal.

STERCULIACEE.

The collection contains a number of cauliflorous species of
Cola. Among the novelties there are two which are of special
interest. In Cola schizandra sp. nov. the anthers instead of
being in a continuous ring in the male flowers are cut up into
phalanges, and for this I venture to propose a new subgenus—
Schizocola. Cola schizandra is allied to Cola digitata Masters,
but I have been unable to obtain male flowers of this latter plant
to dissect. The other novelty to which attention should be
called is Cola gigas sp. nov. with flowers 7-8 cm. long. The
exact affinity of the latter plant is somewhat doubtful at present,
as it is not closely allied to any other member of the genus; it
is evidently à most striking novelty.

Two other novelties are Cola Talbotii and Cola Buntingii,
both members of the subgenus Cheirocola, the latter collected by
Mr. R. H. Bunting in Liberia. Another novelty is C. arcuata

belonging to the subgenus Haplocola, and allied to C. flavovelutina
K. Schum. and C. Gilgiana Engler.

with wool at first, perhaps glabrous eventually. Flowers crimson-
purple, large, 7-8 em. long, showy, arising two or three together from
the stem.

The distinguishing features of this species are the 5-foliolate
lobed leaves with sessile leaflets and a long petiole, the intermediate
leaflets are 40-45 cm. long, the exterior leaflets much shorter; the
large flowers arising from the old wood in clusters of two or three;
the ellipsoidal urceolate calyx 5-lobed towards the apex, 7-8 cm. long.

Axis of leaf about 7 dm. in length, swollen quite at the base,
fistular, purplish-brown, shining. Leaflets usually 15-18 cm. long,
4-5 cm. broad, the basal obliquity not very marked and sometimes
absent, greenish-brown when dry above, brown below, on both
faces palely lucent; lateral nerves prominent on the underside,
usually 6-8 on each side of midrib, openly arched, anfractuose
towards the margin of the leaf; petiolules 5-7 mm. long. Panicle
30 cm. or more in length, its branches ascending or patent, and some-
times so patent that the panicle may measure nearly 40 cm. across ;
main axis as well as branches ancipitous. Flowers 6 to the fascicle
or less; bracts about ‘3 mm. long, like the 3-4 mm. long pedicels
tawny pubescent. Functionally male flowers alone seen. Calyx
nearly 2 mm. long. Petals 5 mm. long, inserted upon a sort of torus
(gland?) rather more than ‘5 mm. in height. Filaments 5-6 mm.
long, the lower portion of each lying in one of the furrows of the
ovary. Ovary with its four cells reduced to minute resin-filled
cavities, 1*5 mm. long; style "3 mm. long.

Several flowers were examined, but all proved to be males. The
plant may thus possibly be diccious. S i

The short stipe (torus) at the top of which the petals are inserted
passed unnoticed by Engler when establishing the genus. - This stipe
is certainly not present in some of the flowers of N. Staudtii Engl.
examined, but in other cases there seems to be a perceptible interval
between the insertion of the calycine whorl and the petaline. As
N. Staudtii is polygamous, the variation in question may perhaps
have some relation to this fact. It must be added that Ifailed to find
either in N. Staudtiü or in N. Talbotii the dilated, deeply 4-lobed
dise Engler describes. This, too, would therefore appear to be an
inconstant character. : :

lrrespective of certain floral points, the two species can be dis-
tinguished on sight by the different leaflets.— [S. M.]

LEGUMINOSE.

There are six new species of Leguminosz in the collection and
three new varieties. Crotalaria Parsonsii sp. nov. (Section
Simplicifolie) is a near ally of C. Vogelii Benth. and C. lineari-
folia De Wild. Baphia obanensis sp. nov. belongs to the Sect.
Delaria and has racemes of flowers from the old branches. There
are two species of Angylocalyx. Dr. Taubert described this genus
in Engler's Bot. Jahrb. xxiii. 172 (1897), the short racemes of
flowers coming from the old wood and the ovary being adnate to
the dorsal side of the calyx-tube. In the Flora of Tropical
Africa, ii. 254, my father described Sophora oligophylla, but this
belongs to Angylocalyx, and as the plant is in the present
collection, n. 1251, I give a description of it under this genus.
There is a very fine new species of Berlinia, which I have named
B. Craibiana, and a new Macrolobium.

leaves and acute, not blunt, apex of the carina.

The distinguishing features of this plant are the terete, hirsute,
branched stem 1-1°6 metre high; the linear-lanceolate, hirsute leaves
with a petiole 2-4 mm. long; the rather lax, virgate racemes of
rather small, yellow flowers; the carina + 7-9 mm. long, bent at a ~
right angle with a slender rostrum.

MYRTACEZ.

The collection contains a very curious and interesting new
genus Crateranthus, allied to Asteranthos and Napoleona. It
differs from Napoleona, as will be seen from the figure, in the
stamens and other characters. Some of the most interesting
plants in the collection are the new species of Napoleona. In the
species of this genus which have been hitherto described the
flowers are solitary or in twos or threes, but Napoleona Eyertonii,
one of the new species in the present collection, has a paniculate
inflorescence, and in two other novelties the flowers are in

30 SOUTH NIGERIAN PLANTS

clusters of 5-30. In Napoleona parviflora sp. nov., the leaves
are small, glaucous and very acuminate, and the flowers are
small. I have included the description of Napoleona Gossweileri
sp. nov., which is strikingly different from the other species of
the genus. It comes from Angola, and was collected by
Mr. John Gossweiler.

This interesting novelty is intermediate in structure between the
genera Napoleona and Asteranthos a Tropical South American genus.
It differs from Napoleona in having only a single whorl between
calyx and stamens, and not 3 as in that genus. It differs from
Asteranthos in the calyx, &e. The terminology of the different parts
of the flower of these curious and somewhat anomalous Myrtaceæ
differs in different botanical works. Dr. Niedenzu, in Engl. & Prantl
Pflanzenfamilien III. 7, considers these plants apetalous. is

RUBIACEÆ (H. F. Wernham) 39

GAMOPETAL.

By H. F. Wernuam, B.Sc.; excepting Composite,
Asclepiadaceze (Loganiacex (in part) ), and Acan-
thacee, by SPENCER MOORE, F.L.S.; and Convol-
vulacex, by Dr. A. B. RENDLE, F.R.S.

RUBIACEE,

This family is the most numerously represented in the whole
collection, and some valuable additions—in the way both of rare
Species already described and of novelties—have been made.
There are 35 new species, and of these six belong to four new
genera— Afrohamelia, Dorothea, Diplosporopsis, Globulostylis—the
two latter including each:two species. Afrohamelia is interesting
as being nearly related to Hamelia, a genus confined to the tropies
of the New World; and its morphology is particularly curious.
The bracts are large and foliaceous, the inflorescences appearing
to arise from the middle of the stalk, to which the peduncle is
adnate ; the leaves are almost exactly similar, but much smaller.’
Dorothea, a near ally of Randia, is especially interesting for its
zygomorphic flowers—a rare feature in this family. Sabicea has
yielded as many as four very distinct new species. Bandia
Talbotii has large showy flowers 21 decimetres long. Coffea
Talbotii is a curious new species which I have assigned to this
genus only after considerable hesitation ; the fruit is a red
fusiform berry, crowned by the persistent calyx-limb.

Cremaspora Thomsoni Hiern. Hiern’s description (Fl. Trop.
Afr. iii. 126) seems to have been based on immature flowers;
the Talbot specimen (n. 1049) affords excellent material The
corolla-tube is 7 mm. and the lobes 6 mm. long, and the fruit,
hitherto unavailable, is 1*5 cm. long.

Coffea subeordata Hiern. The corolla-lobes and stamens are
much larger than stated in Fl. Trop. Afr. iii. 184, but the Talbot

plant (n. 243) is otherwise identical with the type, and agrees
with the original description in Trans. Linn. Soc. ser. Il. i. 174.

Cephaélis Mannii Hiern n. 154. The peduncles are several
feet long, instead of about 1 foot, as known from previous

specimens.

A very distinct genus, the nearest ally being the tropical American
Hamelia, from which this differs chiefly in the contorted s»stivation
of the corolla and the large two-chambered oblong fruit; the latter
recalls many species of Hamelia in the persistent and conspicuous
disc. The corollas in the two genera are very similar, both in bud
and in open flower; but the characteristically ventricose base of the
tube in Hamelia is absent in our genus. The typically secund
arrangement of the flowers in the American genus does not occur in
the type of Afrohamelia; and the large foliaceous bract subtending
each cyme is distinctive.

up to 2:5 cm. long. Stipular band barely exceeding 1 mm. in width ;
apiculus about the same length. The bracts are 14-17 cm. long and
9-11 em. broad, with stalk 2:5 em. or more long. The cymes, at
most 1°5 cm. long, are borne, on peduncles 2-3 em. long, terminally
on lateral shoots about 1 cm. in length. Calyx less than 1 mm. long;
corolla-tube 9 mm. long, 4 mm. wide above; lobes over 2 mm. long

Stipules (including seta) 5 mm. long. Pedicel about 5 mm. long,
increasing to nearly 1:5 in the fruit. Calyx-limb about 1 mm. long,

A remarkable plant, quite distinct from all other species of Coffea,
especially in the calyx-limb and fruit. The latter characters almost
entitle it to the rank of a separate genus.

The leaves are from 19 to 24 em. long and 6°5 to 8 cm. broad; the
densely hairy petiole is from 3 to 4 em. long. Leaf-veins well-marked
on both sides of the leaf, divaricate, meeting the midrib perpendicularly
and curving upwards until parallel with the margin; the veins are
closely set, 11-14 pairs with nearly the same number of shorter veins
intervening. Stipules 7 mm. or longer, 5-6 mm. broad at the base.
Flowers barely 5 mm. long. Fruit 4-5 mm. in diameter, with a broad
10-furrowed crown.

Its nearest ally is L. batangensis K. Schum., from which it differs
in the much larger and differently-shaped leaves and longer petioles,
in the leaf-venation, in the arrangement of the flowers, and in the size
of the fruit. Our species is apparently identical with the plant
collected by Mann on the Gaboon River (n. 917), preserved in the
Kew Herbarium, although the latter is not quite so hairy (vide Hiern,
in Fl. Trop. Afr. iii. 228). ;

COMPOSITZE by Mr. S. Moore.

Contrary to what is usually found in an African collection,
the Composite form quite an inconspicuous element in the one
under notice, and indeed the Composite flora of Upper Guinea
is a poor one at best. One sees the same relative poverty when
comparison is drawn between Eastern Brazil and Amazonia,
India and the Malay Peninsula, and the interior of Australia
and its northern coasts. In these cases the country more open
in character and drier in climate is the richer in Composite, a
fact of high antecedent probability, seeing that the fruit is edis-
persed chiefly by means of the pappus, and in a moist, densely
afforested district this dispersal would be restricted not only by.
liability of the pappus to collapse, but because the thickly
growing vegetation would form an obstacle to the achenes in
their flight.

Vernonia frondosa Oliver & Hiern (n. 494) is a fine species
hitherto unrepresented in the National Herbarium.

Branches slender, white, with narrow herbaceous wings barely
1 mm. wide. Leaves up to 25 x 4 mm., those on the branchlets.
usually reduced to about 10 x 2mm. Glomerules about 10 mm. in
diameter, composed of a large number of capitula. Peduncles at
most 5 mm. long. ‘Outer bracts 8-4 mm. long, 2 mm. at the widest
part, firm in texture, greyish-green when dry. Bracts of the capitula
8:5 mm. long, "75 mm. broad, somewhat cymbiform, provided with
short stiff hairs near the apex on the outer side. Involucral leaves
3 mm. long, like the bracts scarious. Corollas of the hermaphrodite
florets pale purple, 1'5 mm. long, the same length as those of the
filiform female florets, which stand on exceedingly slender pedicels
1-1:5 mm. in length. Young achenes 2 mm. long, papillose. Achenes
of the female florets 1 mm. long, covered with spreading hairs.

This might be mistaken on a first view for S. peduncularis DC.
which inter alia has 6-leaved involucres. Its position in the genus is
near S. Steetzii Oliver & Hiern.

Centaurea Perrottetii DC. is referred in the Flora of Tropical
Africa to C. Calcitrapa—wrongly, I think. The single specimen
-in the collection (n. 1007) agrees fairly well with C. Perrottetii,
' and still better with some Nigerian specimens in the Kew
herbarium.

Leaves 17-22 cm. long, 5-5°5 em. broad; petioles 1:7 cm. long;
lateral veins 8-10 pairs, Peduncles to 17 em. long, about 4-flowered.
Bracts about 1 em. long, and the same width in the broadest part.

A slender-stemmed twining plant. Leaves when full grown 4-5 x
2:5-3 cm., exceedingly thin in texture, drying green and markedly
paler beneath, provided with a large number of minute immersed
pellueid glands; petioles 1-2 cm. long, sometimes of unequal length
in the pairs, scabridulous. Cymes short or elongated, sometimes
1 cm., more often 5-6 em. long; in the latter case 7 cm. more or less
in diameter. Common peduncle very short or absent; partial pedun-
cles at most 4 em. long. Pedicels usually 5-8 mm. long. Bracts
about 1 mm.in length. Flowers green. Segments of calyx 1:95 mm.
long. Hapanded corolla 6 mm. in diameter; tube 1:25 mm. long;
lobes 2:5 x 2:5 mm. — Staminal column, including the appendages
to the anthers, about 1 mm. long. Coronal leaves about "4 mm. long,
blackish. Style exserted beyond the staminal column to a length of
nearly 1 mm.

Differs from S. leonense N. E. Br., chiefly in the cordate (not
cuneate) leaves, the glabrous cymes and the conical entire style.

Leaves mostly 6 em. long, 3 em. broad, the narrowed portion at
most 2 cm. long; petioles somewhat twisted at the base, about 3 em.
long. Peduncles also twisted at the base, usually 1:5-3 em. long.
Segments of the calyz becoming patent, 1-2 cm. long. Corolla a
dirty white with purple blotching, the tube almost 4 em. long, 4-5 mm.

To be inserted in the genus next C. Johnsoni N.E. Br., which has
smaller, less deeply cordate leaves, a much shorter calyx and a
Shorter corolla less swollen both at base and throat.

Judging from material to hand, the corolla -varies somewhat in

shape; this may be due to drying; Mrs. Talbot’s excellent coloured
drawing gives but slight evidence of such variation.

Leaves quite small for the genus, about 7 cm. long and 3°5 cm.
broad. The very short petioles have a very broad, almost sheathing
base, and an interpetiolar line is clearly observable at the node.
There are 5-6 secondary veins on either side of the midrib, but these
are usually only faintly discernible on the lower side of the leaf. The
inflorescence just exceeds theleaves. The calyz is barely 6 mm. long ;

the corolla-tube 19 to 14 mm. long, and the lobes about 1 em. long
| and 4 mm. broad. Anthers 6-7 mm. long.

The nearest affinity among the species hitherto described is A.
pulcherrima Gilg, but the present species is at once distinguished
by the shape, size and venation of the leaves, and by the much
smaller flowers.

Leaves small for the genus, 12-15 em. long, 3-6 cm. broad, petiole
5-10 mm. long. A pair of small leaves, 3:5 em. long and 1:8 cm.
broad, usually subtends the inflorescence, which exceeds the foliage-
leaves. Calyx about 1:5 cm. long, outer lobes 6 mm., inner 8 mm.,
broad, strongly concave. Corolla-tube 2 cm. long altogether, of
which the campanulate part exserted beyond the calyx measures

This species approaches A. laxiflora Baker, from which it differs
in the shape and size of the leaves and calyx-lobes.

CONVOLVULACEE by Dr. A. B. Rendle.

The collection includes thirty-four species, sixteen of which
belong to the genus Ipomoea. The majority are more or less
widely spread in Tropical Africa or tropical countries generally.
Eight are restricted to West Tropical Africa, including Lepi-
&temon parviflorus Pilger and Ipomoea Hierniana Rendle, previously
known only from the Cameroons, I. velutipes Welw. from S.
Cameroons and Angola, and I. micrantha Hallier f. from the
Cameroons and. Ashanti. :

Said to be leafless in the flowering and fruiting stage. Peduncles
apparently short, stiff, bearing a large number of crowded flowers;
pedicels 6-7 mm. long. Outer sepals 5-8 mm. long, the outermost in
the fruiting stage to 4'5 cm. long and as broad, the inner about

densely crowded towards the top of the short axillary peduncles.

Merremia pes-draconis Hallier f. var. nigeriea var. nov.
A typo differt foliis magis evolutis, calyce breviore glabro et

River Benue; n. 832.

Leaf-stalks *5 to 3 em. long (8 mm. in the species); blades to
9:5 cm. long (6 cm. in the species); deeply palmately-pinnately
7-lobed (5-lobed in the species). Calyx glabrous, 2 em. long (the
outer sepals are hairy and 12 mm. long in the species). Corolla
2 cm. long (2:7 mm. in the species).

M. pes-draconis is represented only by a specimen “en état
plutot mauvais" in the Brussels Herbarium, collected by Descamps
in the Congo Free State (Kasai distriet). Dr. De Wildeman has kindly
compared a Nigerian specimen with the type; he says, “ It is certainly
near M. pes-draconis, but is distinguished by longer-stalked leaves,
with a more developed limb, more numerous lobes and a more hairy
lower surface, by a more glabrous and shorter calyx and a relatively
reduced corolla." The Nigerian plant may represent a distinct but
closely allied species, but in view of the unsatisfactory character of
the material of M. pes-draconis I prefer to regard the differences at
present as merely of varietal value.

ACANTHACEJ by Mr. S. Moore.

A few genera of Acanthacex, such as Dischistocalyx, Whitfieldia,
Physacanthus, Lankesteria and Thomandersia, are exclusively or
largely West African. Mr. and Mrs. Talbot's discovery of a new
genus (Talbotia) is therefore no matter for surprise.

74 SOUTH NIGERIAN PLANTS

Crossandrella Dusenii S. Moore comb. nov, Syn. Pseudo-
blepharis Dusenii Lindau, Acanthus Dusenii Clarke, Crossandrella
lawispicata Clarke. The Uganda plant which served as the type
of Clarke's Crossandrella laxispicata is identical in every respect
with the plant from the Cameroons.

Adhatoda Buchholzii S. Moore comb. nov. (Duvernoia Buch-
holzii Lindau). Some of the specimens agree with Lindau’s
description, which, the species being unrepresented in this
country, is all one has to go upon. Clarke’s (Flora Trop. Afr.
v. 223) reference of D. Buchholzii to Adhatoda maculata Clarke
(Justicia maculata T. And.) is obviously a mistake, for, to take
only one point, A. maculata has, as Clarke says correctly, lanceo-
late bracts, while Lindau describes the bracts of his plant as
ovate. Moreover in general appearance the two are quite unlike.
The matter has become further confused by Zenker's n. 2229, a
plant with large ovate bracteoles, having been distributed as
* Duvernoia Buchholzii Lindau," whereas Lindau says his D.
Buchholzii has the bracteoles minute (winzig). Furthermore, as
if this were not enough, Zenker n. 2755, a plant with large sub-
orbicular bracts, has been sent out as “Duvernoia maculata
(T. And.) Lindau.”

Speeimens named as above show much variety in their foliage
and braets. Some agree perfectly in these respects with Lindau's
description; others have short and broad leaves rotundate at base and
short stalks, and from these leaves there may be a passage into sessile
sometimes amplexicaul leaves 2:5-5 cm. in length, the uppermost
forming a transition to the oldest bracts. The largest of these latter
organs may be as much as 2 cm. in breadth, thus greatly exceeding
the dimension (7 mm.) given by Lindau. But as these variations may
occur on one and the same individual, there can be no question of
specifie divergence here. The plant is thrown into rivers with the
object of poisoning fish. —

still narrower, but is in many other respects quite different.

A North Cameroons specimen (imperfect) in the British Museum

Dischistocalyx Buchholzii Lindau, appears to come very close to
this. The Cameroons plant does not agree with the description of

white or pale mauve corollas.

Mrs. Talbot tells me the flowers are also sometimes pink. Ono of
the Holland labels at Kew gives the flowers as ** white," the other as
“ pink, yellow centre."

Leaves 7-10 x 8:0—4:5 cm., drying brown-green above and
greyish below ; petioles 1 to nearly 3 em. long, stout, covered with the
same pale fulvous tomentum as the stem. Spikes 5-9 cm. long,
about 1:5 em. broad, the lowest bracts generally entire, 10-13 mm.
long, the upper ones 20 mm. long, 7 mm. broad, all traversed by
several rather prominent longitudinal nerves, with transverse con-
necting nervules. Bracteoles 6 mm. long, like the calyx subscarious
and glabrous. Segments of calyx 9 mm. long, 1 mm. broad about
half way up; midrib prominent, especially at the base, each with
several closely packed longitudinal nerves on either side of the
midrib. Tube of corolla 18 mm. long, nearly 2 mm. wide at the
throat, elsewhere 1 mm. ; lobes about 11:0 x 4:5 mm. Filaments
rather more than 1 mm. long, bearded above. Anthers slightly
curved, 2 lines long. Ovary 2:5 mm. long. Style thickened towards
. the apex, slightly hairy, 2 em. long. Stigma 2-lobed, rather more
than 1 mm. in length.

Readily known from C. puberula Klotzsch and C. guineensis
Nees by the truneate braets and the calyx. The spheroidal pollen
is abnormal, though it should not be forgotten that two quite different
kinds of pollen are found in the neighbouring genus Stenandrium.

Apparently referable to the above, and differing from it only in
the larger and longer-stalked leaves and the larger bracts, are specimens
of Bates, nn. 490 and 546 from Batanga. At Kew the specimens
have affixed to them a MS. name of Pierre, who considered them to
belong to a new genus.

Oban ; n. 101.

A handsome plant about 3 feet high. Leaves up to 16 x 9 cm.,
often about 12 x 6 em., sometimes markedly narrowed at some
distance from the base, i.e., somewhat panduriform, when dry olive-
green above and grey below; petioles 1-2 cm. long, greyish tomentose.
Spike when fully grown about 16 cm. long, the axis covered with a
grey pubescence. Bracts 22-25 mm. long, usually with several
spinulose teeth upon each edge, purple in the living state. Bracteoles
13 mm. long. Larger segments of calyx 9:0 x 1:75 mm., smaller
segments 8:0 x 1°5 mm. Corolla white, with a purple spot at the
base of each posticous lobe; tube barely 80 mm. long, 1:5 mm. broad,
widening to 2 mm. near the top; antieous lobes about 20 x 19 mm.,
posticous 12 x 8mm. Anthers 2:5 mm. long.

This also is near C. guineensis Nees, differing from it in habit, in
the spine-toothed bracts and the calyx. The acuminate bracts serve
to distinguish it on sight from C. Talbotii; but there are other
points, including the pollen, in which the two are diverse.

Oban, Ako-Aking Road; n. 971.

A prostrate rooting herb, the ascending flower-bearing branches
eventually rooting in their turn. Bladeof leaf usually 3-5 x 2:5-3:5cm.,
grey-green when dry, paler below and with an open network of pro-
minent hairy nerves; petioles 1-1:5 (rarely up to 9:5) cm. long.
Bracts about 10 x 7 mm. Bracteoles 8-10 mm. long, 1:75 mm. wide
at the broadest part. Spikes usually 2-4 cm. long, on peduncles of
1-2 em. Calyx about 29:5 mm. long. Tube of corolla 9 mm. long,
3 mm. broad. Upper lip 7:5 x 8 mm.; lower lip 7 mm. long, the
lateral lobes 4:5 x 2 mm., the middle lobe 4:5 x 8 mm. Filaments
of front pair of stamens 4 mm. long, of hind pair 2mm. Anthers
2 mm. long. Pollen-grains about 70 p in diameter (55-80 u). Ovary
1:5 mm. long. Style 12 mm. long. Capsule not seen.

The position of this very distinet genus is somewhat uncertain,
but in view of all circumstances the neighbourhood of Lepidagathis
would seem to be its proper location. It should be observed that the
supposed slit on the inner face of the pollen-grains was not clearly
made out.

Near J. pyramidata Clarke, but with marked differences in shape
of leaves, inflorescence and flowers.

It is said to stupefy fish, like other species of this genus and of

A small plant with the habit of Jerdonia indica Wight, and
other lowly Gesneraceae. Lower part of stem creeping and rooting
at the nodes, upper part ascending, usually simple, but occasionally
throwing out a weak side-branch. Leaves three or four pairs, younger
at» intervals of 5-7 mm., the lower more distant; blade up to
' 6 or 7 em. long and 3:5-8:7 em. broad, but often much smaller,
e.g., 9:0 x 1'5 cm., the nervation very prominent on the underside,
especially in the case of larger leaves; petioles stout, 3-8 mm. long.
Inflorescence of very small specimens reduced to a single lengthily
pedunculate flower, but usually of cymes, which may reach
10 x 6 em., of which 3:5 em. belongs to the filiform peduncle, the
main axis giving off usually 2 pairs of lateral branches, whieh may
themselves braneh again, each branch at the top producing &
cymule of 2-8 subsessile or peduncled flowers, the branches and
- peduncles filiform and pilose-pubescent. Bracts and bracteoles |

A low shrub with lengthy branches sparsely leafy. Leaves usually
7-10 x 3°5-5 cm., but sometimes smaller, e.g., 5 x 9:5 cm., those of
& pair often unequal in size, olive-green when dried; petioles about
5 mm. long, pubescent. Peduncle of thyrsus 7 cm. long. Inflorescence
itself at most 9 cm. long and 3:5 em. in breadth below, narrowing
upwards. Flowers subsessile, produced on one side of the partial
inflorescences. Floral leaves about 5 mm. long. Bracts and bracteoles
1'5 mm. long. Calyx 8 5-4 mm.inlength. Corolla-tube 4 mm. long,
1:5 mm. wide at the base, and but little exceeding 2 mm. at the
throat. Upper lip 4'5 x 2:5 mm.; lobes very obtuse, barely 1 mm.
long; lower lip 4 x 3 mm., its middle lobe 2 x 1:5 mm., the side
lobes 2 x 1mm. Anthers exserted, the upper of either pair of cells
scarcely more than 1 mm. long, the lower including the strong, nearly
straight obtuse white spur almost 2 mm.in length. Ovary 1:5 mm. long.

This has much the appearance of J. laza T. And. and its allies;
its characteristic features are, in association with the thyrsoid fulvous-
pubescent inflorescence, the linear floral leaves and the small flowers.

12 mm. long; bracteoles 2-2°5 mm. long. Limb of corolla purple.
Segments of calyx in flower 6-8 mm., in fruit 8-10 mm. long. Corolla
when moistened 28 mm. long; tube 17 mm. long, + 1:5 mm. broad,
at the throat 2 mm. broad; lower lip 11 mm. long, its lobes 5*5 mm.
long; upper lip 7 mm. long. Upper cell of anther 1:6 mm. long,

At first sight this looks rather like Justicia Galeopsis T. And.,
but the narrower leaves and of course the long corolla-tube are easy
distinguishing features. According to Lindau's views this is an
Aulojusticia, but I agree with Bentham & Clarke in placing the allies
of the plant just described in the genus Siphonoglossa.

The affinity is with B. Brownti S. Moore, a Uganda plant which
it much resembles in leaf and inflorescence. That species, however,
has much smaller and differently-shaped ealyx-segments and corollas,
ete., different in several respects. I am indebted to Mr. Turrill, of

Oban; n. 991.

Slender, divaricate, somewhat anfractuose, trailing branches sub- —
distantly leaf-bearing. Blade of leaf usually 2:5-4 x 1:8-1:7 em.,
at most (and that rarely) 6 x 2'5 cm., brownish-green when dry;
petioles 5-12 mm. long, usually with a few short hairs upon them.
‘Racemes 3-flowered (exclusive of the corollas), 2-5' 5 em. long, including
the 5-25 mm. long pedunele. Pedicels 1-2 mm. long. Bracts and
bracteoles about 1°5 mm. long. Segments of calyx 9 mm. long,
1-8-2 mm. wide in the widest part, often with a few microscopical
hairs on the outer side and with faint traces of ciliation on the margin.
Corolla-tube 20-22 mm. long, when moistened 3 mm. wide near the
base, expanding to 9 mm. at the throat. Lobes 7 x 5-6 mm. Fila-
ments inserted at 7 mm. from base of corolla, the longer pair 5 mm.
long, the shorter scarcely 9 mm. Anthers 1:25 mm. long. Ovary
ovoid, narrowed above and passing into the style, 8 mm. long. Style
glabrous, about 1 em. long.

The affinity of this is with 4. Buettneri Lindau, which is different
in leaf, calyx, anthers, and a few other points of minor importance.

No. 9914, also from Oban, is probably to be referred here, though
its longer petioles, greater number of flowers to the raceme, and strongly
ciliate calyx-segments, are special features.

5 x 7 mm.; petioles 8-20 mm. long. Spikes solitary or one from
each axil immediately beneath the apical bud, erect, 15-18 cm. long
(of which a length of 5-6 cm. belongs to the peduncle) and about 1 cm.
broad. Bracts and bracteoles 5-6 mm. long, those of the upper flowers
somewhat smaller. Segments of calyx 9 mm. long, with faint longi-
tudinal nervation. Corolla-tube 4:5 mm. long, 3 mm. broad, at the
throat contracted to 2 mm. ; upper lip galeate, oblong-ovate, 5*5 mm.
long; lower lip 5:5 mm. long, its lobes oblong, obtuse, and 4:5 mm.

10 x 6 mm. Seeds oval-oblong, with a dark nearly smooth testa,
about 4 mm. long, the curved retinacula ending in a sharp point.

The shape of the leaves and the small flowers with deeply tripartite
lower lip and puberulous filaments are the chief points separating this
from A. tristis Nees.

The upper part of the perianth-tube of this supposed variety is

very long tails there seems no difference. As with the type, no leaves
of this are to hand. The perianth is very pale green in colour with
dark purple spots, and the hairs in the throat are pure white. The
single fruit sent consists of two oblong portions (apparently the two
halves, though the ends do not quite match), each 10 em. long and

By Dr. A. B. RENDLE, F.R.S. (excepting Zingiberaceae
by H. N. Ribrey, C.M.G. F.R.S.).

ORCHIDACEE.

The collection contains seventy species, of which twenty are
new. Their affinity is almost exclusively West Tropical African,
and as might be expected a large proportion occur also in the
Cameroons, seventeen species being hitherto known only from
that area. Among these is the genus Auxopus recently described
by Dr. Schlechter from a single locality. Nineteen species have
a wider distribution through the region bordering on the Gulf of
Guinea from Sierra Leone to Gaboon, including Prince's Island
and the Island of St. Thomas; Habenaria barrina Ridl. has
hitherto been known only from St. Thomas. A smaller number,
seven, are more generally West Tropical African, extending
southwards to the French Congo or Angola.
Platanthera helleborina Rolfe and Habenaria procera Lindl.
are interesting additions, being previously recorded only from
Sierra Leone, the latter known apparently only from Lindley’s
figure (Bot. Reg. t. 1858), with which the Nigerian specimen
agrees. Two of the new species belonging respectively to
Bulbophyllum and Habenaria have also been sent from Liberia
by Mr. R. H. Bunting.
It is with much regret that I have felt compelled to quote
the species of Listrostachys and Mystacidium under Angraecum.
Dr. Schlechter has recently given repeated instances of cases
where the affinity deduced from general characters is at variance
with that deduced from the single character of the pollinia and
their appendages; species obviously closely allied must be
artificially separated on this criterion. The multiplicity of names
borne by many of the species is an indication of the unsatisfactory
nature of the system which continues to maintain this distinction.
An example is afforded by the species which I originally described
as Listrostachys clavata; the pollinia were attached by their
caudicles to a single gland, which, however, being easily separable
into two parts, was on this account referred by Mr. Rolfe to
Mystacidium. More recently Dr. Schlechter, in describing a new
species, Angraecum affine (in which the two pollen-stalks are

attached to a common gland), mentions as its nearest ally the -

*

species in question, which he calls A. clavatum. Unfortunately
the trivial is already occupied in Angraecum, so a new one must
be found for my original plant. I have suggested multinominatum.

The somewhat stout widely branching stem is attached on the
lower portion by numerous stoutish branching roots, the surface of
which is densely covered with minute whitish papille. Stem and
branches are incomplete in the specimen (a somewhat withered one) ;
the main axis measures 4:5 dm. Internodes barely 1:5 em. long,
about 4 mm. thick. Leaves 5-6:5 cm. long, 7-9 mm. broad. The
flowers are described from a few detached specimens; no trace of the
inflorescence remains except the basal attachment penetrating the
leaf-sheath. Sepals 7 mm. long, barely 8 mm. broad. Petals 6:5 mm.

reaching 4:6 dm. in height with a thickness of 3 mm., the large
radical leaves 15 em. long (including the lax sheathing base) by 3 em.

leaves 6-10 cm. long and a shorter, laxer-flowered spike. Fertile
bracts 12-18 mm. long. Dorsal sepal 5-6 mm. long, 2 mm. broad;

Apparently (from the description) allied to H. physuriformis
Krünzl. from the Cameroons, but a larger plant with larger flowers.
Kränzlin (in Engl. Jahrb. xliii. 395) places this in his section Replicatae,
though the petals are deseribed as undivided; it would seem more
fitly placed in the section Tridactylae.

Habenaria barrina Ridl. in Bolet. Soc. Brot. v. 202. Oban :
n. 923. A single specimen which is of interest as the species has
hitherto been known only from the Island of St. Thomas. By
some misunderstanding Rolfe (in Flor. Trop. Afr. viii. 230)
cites the species as a synonym of H. thomana Reichb. f. The
two plants differ remarkably in habit; H. thomana has a tuft of
rather large radical leaves, while the cauline leaves pass rapidly
into bracts ; in H. barrina, on the other hand, there are no radical
leaves, and the lower part of the stem bears reduced leaves which
pass above into the more or less lanceolate foliage-leaves occupying -
the upper part of the stem almost to the base of the inflorescence.
The flowers also differ in the two species: in H. thomana the two
divisions of the petal are strikingly unequal, in H. barrina nearly
equal ; in H. thomana the lateral lobes of the lip are comparatively
broad, falcate and retuse, in H. barrina slender, resembling the

median lobe ; the length of stigmatic processes and anther-canals
is also very different in the two species.

This species is allied to C. lateriflorus Baker in its lateral inflor-
escence which is unusualin the genus. It differs from that species
in its narrower elliptic less coriaceous leaves, the presence of large
ovate bracts on the capitulum and smaller flowers. According to
the field-notes the bracts are bright transparent pink, paler, almost
white, at the base; the corolla white, with bright yellow in the
mouth of the lip. z

Halopegia azurea K. Schum. There are a number of
specimens and three sketches of Halopegia which ditfer somewhat
in appearance. We have first the typical form, in which the _
flower-spikes are still enclosed in the sheath of the subtending

E12 SOUTH NIGERIAN PLANTS

leaf, but emitting their flowers. The drawing of this form gives
the flowers of a pure blue. These resemble closely the types of
the plant as described by Schumann, collected in the Cameroons
by Preuss (n. 352) and in the East Gaboon by Bates (n. 548).

The second drawing (n. 57) shows a plant differing in that
the spikes are freed from the leaf-sheath and spreading sub-
horizontally. The flower here is given as of a lilac colour. The
specimens corresponding to this drawing resemble those of the
typical H. azurea except that the spikes have spread from the
sheath. In other specimens the spikes in two or three fascicles
are quite free and spreading, and elongated to as much as 30 em.
I conclude that these are only a later stage development of the
form which commences to flower before the spikes are actually
free of the petiole-sheath. The flowers are very thin and
fugacious and preserve ill ; the foliage and fruit, however, are the
same in all.

A third form or state has a single spike emitted directly from
the rhizome without any of the basal leaves or sheaths developed
into true leaves. The few specimens are rather poor, and the
drawing is only a pencil sketch. It is quite possible that this is
a distinct species, but it may be an occasional sport of an
inflorescence in which the foliar stem has been suppressed or not
evolved. A similar modification occurs occasionally in Globba,
Costus afer, C. speciosus and other members of the family.

This interesting and charming genus whose distribution—
Africa, Burma and Java—is peculiar, requires further in-
vestigation,

ARACEÆ.

The species collected are mainly restricted to the Gulf of
Guinea area, and are useful in extending our knowledge of the
distribution of the species concerned. Such are Amorphophallus
accrensis N. E. Br., from the Gold Coast, a fine specimen with
an appendix to the spadix nearly 7 dm. long and 6°5 cm. thick
just above the base, Nephthytis Poissonii N. E. Br., Anubias
lanceolata N. E. Br. and Raphidophora pusilla N. E. Br., from the
Cameroons and Gaboon; Anubias Afzelii Schott has hitherto
been recorded only from Sierra Leone. Anchomanes nigritianus
is a new species with a striking inflorescence. Other novelties
are Nephthytis Talbotii and Amauriella, a new genus allied to
Anubias, but distinguished by the character of the andræcium.

CYPERACEÆ.

The collection contains only four species, three of which are
distributed in West and Central Tropical Africa; the fourth
Mapania amplivaginata K. Schum. has hitherto been recorded
only from the Cameroons.

GRAMINEÆ.

Comparatively few grasses were collected, and these are
mainly of wide distribution in the tropics. Two of special
interest are Guaduella Ledermannii Pilger and a specimen which
is probably identical with G. Zenkeri Pilger; both these have
been previously recorded only from the Cameroons.

FUNGE

By J. RAMSBOTTOM, B.A.

Lentinus Tuber-regium Fr. The first description and illustra-
tion of this fungus is by Rumphius (Herb. Amboin. vi. lib. xi.
120, t. 57 (1750)). The figure represents what seems to be a
smooth block of earth on which six agarics are growing.
Rumphius calls the former Tuber-regium and the latter Boleti.
He gives a long account of the Tuber: it is very common in
spring and autumn during the rainy seasons, and it is then quite
soft and not durable. When planted and watered with warm
water it produced the Boleti, but perished the next year. In
size it varies from the size of a man’s fist to that of a child’s
head. A list of native names for the Tuber is given and it is
stated that it is quite common in certain islands, under grass on
the mountains and at the roots of tall trees. In spite of this
statement it seems that it has not been again met with in the
East Indies.

Fries in his Systema Mycologicum i. 174 (1821) places the
“ Boletus” in the genus Agaricus and gives a diagnosis drawn up
from Rumphius’ description. He queries whether the * matrix "
is Scleroderma, but later (Syst. Mycol. ii. 243 (1823)) he places it
with Selerotium Cocos in his new genus Pachyma. Afterwards
in the Epicrisis (392 (1836-8)) the fungus becomes Lentinus
Tuber-regium : the statement * non vidi” is added.

The next record of L. Tuber-regium is apparently that of
Hennings, in Engler Bot. Jahrb. xiv. 351 (1891). He records
two specimens, one from Mombassa and one from the Cameroons,
and gives a description of the fungus which has been found
several times since in the latter district.

In the present collection there are eight specimens of
L. Tuber-regium, representing a series from the youngest stages
where the fruit appears as a small cone of tissue (Pl. 17, fig. 1) to
large specimens over 20 cm. across the cap. In only one case is
there a perfect sclerotium, which is an irregular structure
measuring in its greatest dimensions 16 x 15 x 10 cm. This
bears nine fruit bodies, one of which is very much larger than
the others (cf. Rumphius—“ Boletus crescit aliquando simplex,
aliquando duplex, aliquando plures simul, quorum tamen semper
unus maximus est") There seems little doubt that the fungus

118 SOUTH NIGERIAN PLANTS

is Rumphius’ Tuber-regium, and also that it is the one described
by Hennings. There are, however, one or two facts which may
be added to Hennings’ description. The squamules which are
present in such quantity on the young pileus do not later
disappear. Owing to the expansion of the pileus they become
widely dispersed and smaller, but in the largest specimen in the
collection with a pileus 24 cm. across the squamules can still be
clearly seen. The gills bifurcate at the base and undergo further
divisions and anastomoses, but the exact procedure has not been
made out. The greatest length of stipe is 13 cm., the greatest
width 2:5 em., and the greatest height of a fungus, excluding
the sclerotium, 28 cm. The felt of the stipes (which has quite
disappeared from the oldest specimens) is usually a dirty fawn
colour. Hennings describes it as “ weiss." In a spirit specimen,
the colour is in places much darker, the upper parts of the stipes
having dark squamule-like patches while the bases are almost
black. The stipe is usually equal but sometimes attenuate
upwards.

In the case of the complete sclerotium, the surface is very
uneven ; on the projecting areas the colour is usually dark brown
or black ; where hollows oecur the surface is clothed with a felt
which is similar in appearance to that on the stipe. On the
upper surface of the sclerotium there are some adhering wood
fibres which may be of significance with regard to the habitat.
In section the sclerotium has a white chalky appearance.

In 1891 Cohn and Schroeter (in Abhandl. Naturw. Verein
Hamburg xi. 4) described a new species of Lentinus, L. Woer-
manni, which they had succeeded in growing from a sclerotium
also obtained from the Cameroons. Their figures of the fungus
resemble greatly the stage of L. Tuber-regium shown in fig. 2.
The only point of distinction is the colour of the stipe which is
almost black, but, as stated above, one of the specimens of the
present collection, preserved in spirit, bears three fruiting bodies
with very dark stipes. The resemblance between the two fungi
extends to the microscopie structure. In neither case have
spores attached to the basidia been demonstrated. The hyphae
of the trama in L. Woermanni were about “2 mm." [2 p] broad
and thick-walled. In the specimens of L. Tuber-regium examined
they are 2-3 u wide; the club-shaped basidia are a little longer
and measure 3-4 u across. The cystidia, as in L. Woermanni,
are usually merely a little longer and wider than the basidia, but
at times they project rather more above the hymenium; the

_ greatest width measured was 7 u. The shape of the cystidia is
however quite characteristic and agrees exactly with Schroeter's
description, “am Scheitel kegelförmig zugespitzte Cystiden, an
deren Scheitel sich kleine, etwa 2 mm. [2 u] breite kugelfórmige
farblose Zellen bildeten, die sich schliesslich abgliederten."

FUNGI (J. Ramsbottom) 119

Moreover the microscopic structure of the sclerotium in
L. Tuber-regium is exactly similar to that described by Schroeter,
and afterwards by Bommer, in L. Woermanni. The internal
tissue is of two kinds: (1) hyphae 2-3 „ wide, undulating,
knotty, geniculate but little ramified ; and (2) globose, elliptical
or elongate structures 10-20 p in diameter. With regard to the
exterior Schroeter recorded one thin layer composed of brown,
strongly interwoven filaments 3-4 u wide, with a very narrow
lumen. Bommer noted a more marked differentiation at the
exterior of the sclerotium: an outer layer 50 p thick of cells
with sclerotised walls, consisting of an inner and outer portion ;
beneath this a second layer about 75 p thick with the hyphal
walls less sclerotised. The same differentiation has been observed
in certain sections of the sclerotium of L. Tuber-regium, but the
layers are not at all so definite as Bommer’s account would
suggest.

The felt in the hollows of the sclerotium, first noticed by
Bommer, is similar to that of the stipe. In both instances it
consists of straight hyphae usually about 2 p wide with very
refringent contents.

In 1901 Massee (in Kew Bull. 163) published a new species,
Lentinus flavidus, from Old Calabar. The pileus is described as
smooth, the stipe as “ densissime velutino-hispidulus, brunneus,”
the spores as elliptical 10 x 44. The fungus grows singly from
a sclerotium. Miss Wakefield (in Kew Bull. 1912) records the
same fungus from Nigeria and suggests that it may possibly be
the same as L. Tuber-regium; she kindly showed me the two
specimens at Kew, and there is not the slightest doubt that both
are young specimens of L. Tuber-regium. In the type-specimen
of L. flavidus the squamules are not very well marked, but they
are distinctly present. :

It is evident that the plant which was described by Rumphius
and so long lost sight of, is fairly common in West Africa, and
it is probable that L. Woermanni Cohn & Schroet. and certainly
that L. flavidus Mass. are merely stages of the same fungus.

Two other species of Lentinus which grow from sclerotia,
L. Cyathus B. & Br. and L. scleroticola Murr., have also been
examined. The types are in the National Herbarium. They
are quite distinct from one another and from L. Tuber-regium.

Polystietus sacer Fr. This specimen shows an interesting
abnormality. A single stipe starts from the sclerotium, which
bifurcates a little above halfway. The main stipe evidently grew
the more quickly and formed a normal pileus. The branch,
though slower in growth, apparently continued to grow some
time longer as it has forced its way through the first formed
pileus, and then produced a second normal one over it.
